Aroostook County, ME: flood risk, in FEMA's own numbers
On FEMA's National Risk Index, Aroostook County scores at the 76.1th percentile for flood hazard, rated "Relatively Moderate", a middling flood hazard by national standards. The hazard here is driven by inland rivers and flash flooding rather than the coast, FEMA's model puts a flood event here at about 3.3 times a year. This describes the county, not any one street, FEMA only publishes exact parcel zones through a live map service.
Aroostook County's flood-insurance compliance gap
FEMA's own figures for Aroostook County report more NFIP policies in the mapped flood zone than FEMA's own count of residential structures there, which produces a compliance rate over 100%, a data problem on FEMA's side, not evidence that everyone here is over-insured. See the data quality guide for how widespread this is. Looking beyond the mandated zone, 0.3% of all residential structures in Aroostook County carry flood coverage voluntarily or otherwise, relevant because most NFIP claims nationally come from outside the mapped SFHA.
